Abstract: Abstract of thesis entitled " Novel Resource Allocation Schemes in Optical Burst Switching Networks" submitted by Li Guangming for the degree of Doctor of Philosophy at The University of Hong Kong in September 2006 Optical communication systems will play an important role in the next generation network. At present, there are three major candidate solutions for optical communication systems based on wavelength-division multiplexing (WDM) technology: optical circuit switching (OCS), optical packet switching (OPS), and optical burst switching (OBS). Given the limitations of current optical processing capability and lack of practical optical buffers, OBS is considered to be the top choice for the next generation network in the near term since it is more efficient than OCS in terms of wavelength utilization efficiency and it does not require the technological breakthroughs needed to make OPS a reality. The main objective of our research is to develop novel resource allocation schemes to improve network performance in OBS networks. We start with a comprehensive review of existing research in OBS networks. We then present the relationships between network performance and network parameters in OBS networks, and provide the guidelines for choosing variousreservation schemes and scheduling algorithms in OBS networks. Switching constraint resolutions are proposed to alleviate the negative effects due to switching configuration time. Next, we propose a window-based reservation scheme and the use of regional controllers to reduce burst contentions. The advantage of using regional controllers and the window-based reservation scheme is that they can be implemented in a generic OBS network and only increase the electronic processing. Simulations show that the proposed schemes can improve network performance even if the network is heavily loaded. Then, we propose a straightforward reservation scheme, dynamic offset, in OBS networks with fiber delay lines (FDLs). Simulations show that the proposed scheme has lower loss probability than the general scheme. We further study the problem of dimensioning fiber delay lines and present the impacts of their parameters on network performance. Finally, we propose a delayed reservation decision scheme in OBS networks with FDLs. Simulations show that the proposed scheme can improve network performance compared with existing schemes.

Available in PDF, EPUB and Kindle. Book excerpt: Next-generation high-speed Internet backbone networks will be required to support a broad range of emerging applications which may not only require significant bandwidth, but may also have strict quality of service (QoS) requirements. Furthermore, the traffic from such applications are expected to be highly bursty in nature. For such traffic, the allocation of static fixed-bandwidth circuits may lead to the over-provisioning of bandwidth resources in order to meet QoS requirements. Optical burst switching (OBS) is a promising new technique which attempts to address the problem of efficiently allocating resources for bursty traffic. In OBS, incoming data is assembled into bursts at the edges of the network, and when the burst is ready to be sent, resources in the network are reserved only for the duration of the burst. The reservation of resources is typically made by an out-of-band one-way control message which precedes the burst by some offset time. By reserving resources only for the duration of the burst, a greater degree of utilization may be achieved in the network. This book provides an overview of optical burst switching. Design and research issues involved in the development of OBS networks are discussed, and approaches to providing QoS in OBS networks are presented. Topics include: - Optical burst switching node and network architectures - Burst assembly - Signaling protocols - Contention resolution - Burst scheduling - Quality of service in OBS networks

Available in PDF, EPUB and Kindle. Book excerpt: Optical Networks - Architecture and Survivability, is a state-of-the-art work on survivable and cost-effective design of control and management for networks with IP directly over Wavelength Division Multiplexing (WDM) technology (or called Optical Internet). The authors address issues of signaling mechanisms, resource reservation, and survivable routing and wavelength assignment. Special emphasis has been given to the design of meshed, middle-sized, and wavelength-routed networks with dynamic traffic in the optical domain, such as the next-generation Metropolitan Area Network. Research and development engineers, graduate students studying wavelength-routed WDM networks, and senior undergraduate students with a background in algorithms and networking will find this book interesting and useful. This work may also be used as supplemental readings for graduate courses on internetworking, routing, survivability, and network planning algorithms.

Available in PDF, EPUB and Kindle. Book excerpt: COST – the acronym for European COoperation in Science and Technology – is the oldest and widest European intergovernmental network for cooperation in - search. Established by the Ministerial Conference in November 1971, COST is presently used by the scientific communities of 35 European countries to coop- ate in common research projects supported by national funds. The funds provided by COST – less than 1% of the total value of the projects – support the COST cooperation networks (COST Actions) through which, with € 30 million per year, more than 30,000 European scientists are involved in - search having a total value which exceeds € 2 billion per year. This is the financial worth of the European added value which COST achieves. A “bottom up approach” (the initiative of launching a COST Action comes from the European scientists themselves), “à la carte participation” (only countries interested in the Action participate), “equality of access” (participation is open also to the scientific communities of countries not belonging to the European - ion) and “flexible structure” (easy implementation and light management of the research initiatives) are the main characteristics of COST.
